Improvement of load-margin and bus voltage of Bangladesh power system with the penetration of PV based generation

As the conventional sources of energy (example. oil, gas, coal) are decreasing day by day in the world, renewable energy is going to be the leading energy source in the future. Among all the sources of renewable energy solar PV generation is the potential source for generating power. Penetration of significant amount of solar photovoltaic generation is a challenge for power system stability. Solar PV systems are totally different from conventional synchronous generator. This paper shows the consequences on Bangladesh power system static voltage stability due to large-scale photovoltaic generation. First, the model of PV based generator has been discussed. Then system-loading margin is studied without and with connecting PV based generator. At last the contribution of PV based generator on solving under voltage problem and improving bus voltage is also discussed in the paper.
